Rose propagation might seem like a task best left to professional growers, but as Jason from Fraser Valley Rose Farm demonstrates, getting free roses from cuttings is a simple and rewarding process that anyone can try at home. In this guide, Jason walks viewers through an easy method that uses everyday household items to create a humidity dome – an updated take on the classic milk jug method.
This practical technique allows rose enthusiasts to propagate their favorite garden roses without needing a greenhouse or specialized equipment. Whether you’re eyeing landscape roses or potted varieties, this approach offers an accessible way to expand your rose collection.
Why the Milk Jug Method Works for Rose Propagation
Propagation by cuttings relies heavily on maintaining humidity around the developing roots, a process that can often feel tricky for home gardeners. The milk jug method mirrors the concept of misting systems or professional propagation tents by creating a small, controlled environment. By cutting the bottom off a milk or water jug and placing it over the cuttings, the humidity necessary for successful root formation is easily retained.
Jason typically propagates roses in a greenhouse under mist, but in this demonstration, he shows that the same results can be achieved with simple materials like a plastic jug, a Tupperware container, and toilet paper rolls. This method not only simplifies the process but also makes it highly affordable.
Selecting the Right Cuttings for Propagation
Jason emphasizes the importance of selecting the right rose stems for propagation. He recommends choosing stems that are either in bloom or just past bloom, as this indicates that the wood is mature enough to root successfully.
For this demonstration, Jason selected a rose with both long stems and flowers. He points out that while flower-heavy sections may look appealing, they are not ideal for cuttings. Instead, look for stems that are pliable but not overly woody – a sign that the cutting is at the right stage of growth.
Best Timing for Cuttings
The ideal time for taking semi-hardwood cuttings is late spring through summer. This period, when roses are actively blooming, ensures that plenty of stems are at the right stage for cutting. Additionally, propagating during this window allows enough time for roots to develop before colder weather sets in, increasing the chances of successful overwintering.
Building the Simple Propagation Setup
Creating this propagation setup at home is remarkably straightforward. Here’s how Jason assembled his system:
Materials Needed:
- A 4-liter (1-gallon) milk or water jug
- A 6-inch Tupperware container (bottom only)
- Toilet paper rolls
- Potting soil (Jason uses Pro-Mix, but any well-draining potting mix will work)
- Rooting hormone (optional but beneficial for faster rooting)

Steps:
- Cut the bottom off the milk jug to create a dome.
- Fill the toilet paper rolls with potting soil and pack them lightly but firmly.
- Place the soil-filled rolls upright in the Tupperware container.
- Take rose cuttings about 4 inches long, trimming just below a leaf node.
- Dip the base of each cutting in rooting hormone and place it into the soil-filled rolls.
- Arrange the cuttings close together to maximize space.
- Mist the inside of the milk jug and place it over the cuttings to create the humidity dome.
The setup is then placed in a room with consistent temperatures around 21°C (70°F) and indirect light, which is crucial for preventing overheating.
Caring for the Cuttings
Jason highlights the importance of regular care during the early stages of propagation. He recommends misting the inside of the jug just enough to maintain a light condensation on the dome, typically checking every 2 to 3 days. This small but essential step ensures the cuttings do not dry out before roots have a chance to develop. This is really just a variation on the humidity dome method, discussed in its entirety here.
After about two weeks, Jason notes that some leaves may yellow or drop – a normal response as the cuttings focus energy on forming roots. By gently removing yellowing leaves, the plant can redirect energy toward root development.
Root Development and Transplanting
Jason’s cuttings typically show early root development within three weeks. At this stage, roots can often be seen growing through the toilet paper rolls, indicating they are ready for transplanting. Rather than disturbing delicate roots, Jason pots the entire roll directly into larger containers, allowing the paper to break down naturally.
Initially, the cuttings are potted into 5-inch pots with bark-based potting mix, but any standard potting soil will suffice. Over the following months, Jason repots the young roses into larger containers, allowing them to grow until they are ready to be planted in the garden.
Post-Rooting Care and Hardening Off
Once rooted, the care of young rose plants is crucial to their long-term success. Jason recommends gradually exposing the newly rooted cuttings to outdoor conditions to harden them off. This process involves placing the pots in a sheltered outdoor location for a few hours each day, gradually increasing their exposure to sunlight and wind over a period of 7 to 10 days. Hardening off ensures the young roses are resilient enough to withstand the harsher conditions of the garden.
Watering should be done carefully, ensuring the soil remains moist but not waterlogged. Fertilization can begin about a month after transplanting, using a balanced liquid fertilizer at half strength. Jason suggests starting with a 3-1-2 ratio or an equivalent, similar to what is used for adult roses. As the plants establish, gradually transition to full-strength fertilizer around the time of the first transplant. This supports steady growth without overwhelming the young roots.
The Results
The final result is a fully rooted, blooming rose that mirrors its parent plant in beauty and vigor. Jason shares the gratifying outcome of this method, showcasing a healthy rose in full bloom, ready to thrive in the landscape. Some of these propagated roses have already been sold, underscoring the effectiveness and efficiency of the process.
Key Takeaways
The milk jug method proves that rose propagation doesn’t need to be complicated or costly. By using everyday items, gardeners can successfully root new roses at home, even during the colder months. This method highlights Jason’s practical approach to gardening, providing a valuable technique that anyone can try.
For gardeners curious about propagation, Jason encourages experimentation with this simple method, inviting viewers to reach out with questions or share their experiences. With a little patience and care, propagating roses at home can become a satisfying and productive part of the gardening journey.
